Grape plant named ‘ARRATWENTYNINE’

ABSTRACT

A new distinct variety of grapevine named ‘ARRATWENTYNINE’ abundantly forms attractive large firm and meaty seedless berries with a red skin coloration; in medium-large clusters which display a sweet apple flavor. The fruit commonly is ready for harvesting during June in San Joaquin Valley of Central California, U.S.A, and displays good eating qualities as a table grape. The fruit firmness renders the fruit well amenable for handling, shipping, and storage.

Classification: The present invention relates to a new Vitis viniferaGrapevine.

Variety denomination: The new Grapevine has the varietal denomination‘ARRATWENTYNINE’.

BACKGROUND OF THE INVENTION

A breeding program was initiated during the late 90's near Bakersfieldin San Joaquin Valley of Central California. In 2006, during thisbreeding program, a new variety of Vitis vinifera was created bydeliberate cross breeding of two parent plants by emasculation of thepollen bearing organ of the female and introducing pollen from anothermale origin. The female parent of the new variety was the A.3. which isa medium red very productive grape variety with a large seed trace(non-patented in the United States). The male parent (i.e. the pollenparent) of the new variety was GAW5 which is a large white crisp,seedless grape variety with medium fertility (non-patented in the UnitedStates).

The parentage of the new variety can be summarized as follows:A.3.×GAW5

An artificial pollination was created, and the result was an embryowhich possessed unique genetic qualities. The rudiments resulting fromthe above pollination were embryo rescued.

In 2007 the plant was transplanted to Bakersfield in San Joaquin Valleyof Central California.

It was found that the new grapevine of the present invention possessesthe following combination of characteristics:

-   -   (a) Forms attractive large firm and meaty seedless berries with        a red skin coloration; in large clusters which display a sweet        apple flavor,    -   (b) Commonly bears fruit during the month of June in the San        Joaquin Valley of Central California, U.S.A., and    -   (c) Bears fruit that is firm and is well amenable for storage,        handling, and shipping.

The new variety during observation to date has displayed no visibledisease, and has displayed an ability to well resist cold, drought,heat; but sensitive to direct exposure to sun and wind. The fruit of thenew variety has been found to display excellent handling and shippingqualities combined with desirable dessert eating qualities.

The new variety of the present invention has been found to undergoasexual propagation beginning in 2009 near Bakersfield in the SanJoaquin Valley of Central California, U.S.A. by grafting on matureThompson rootstock (non-patented in the United States). Such asexualpropagation has been conducted thereafter in successive years through2010, and has shown that the characteristics of the new variety arestrictly transmissible from one generation to another. Accordingly, thenew variety undergoes asexual propagation in a true to type manner.

SUMMARY OF THE INVENTION

The new variety ‘ARRATWENTYNINE’ is a large red seedless table grapewith a medium-high production, e.g., about 32-36 bunches per vine, andan average of about one to two bunches per shoot.

Asexual reproduction by micro propagation of the new variety asperformed near Bakersfield, Calif., U.S.A., shows that the forgoing andother distinguishing characteristics come true to form and areestablished and transmitted through succeeding propagations.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying photographic illustration shows typical specimens ofvegetative growth of six year old specimens of the new variety, in coloras nearly true as it is reasonably possible to make in a colorillustration of this character. Colors in the photograph may differ fromthe color values cited in the detailed botanical description below,which accurately describes the colors of the new Grapevine.
